sudo apt purge nvidia-dkms-390 successful in also removing nvidia-driver-390*.
However, sudo apt install nvidia-driver-390 results in same error condition of
"Errors were encountered while processing:
 nvidia-dkms-390

Same for me here using disco...

Status changed to 'Confirmed' because the bug affects multiple users.

Update:
With today's update - kernel 4.18.0-11-generic and new nvidia files - the 390 version driver does install however does not load.
see the attached /var/log/Xorg.0.log, and /var/log/gpu-manager.log .
What is promising is 'lshw' shows the nvidia driver as loaded/

Rather confusing as to what is going on.

Try and push this along.
Is this a packaging error ? As the Xorg file indicates:
4.976] (==) ModulePath set to "/usr/lib/xorg/modules"

However, the nvidia directive does not exist there:

Mind you, I do not know, but seems logical the nvidia_drv.so should be pointed to.
